I suppose what seemed like a nice product/customer service feature ended up equating to additional overhead cost per blade and meant the blade would likely last longer if used, equating to reduced sales frequency. Bad for business double header.
i order the roll of silicone rubber and installed that on the blade. In Arizona the rubber always went bad before needed and the silicone is now 4 years old. That might be an option
Refills in silicone
